N-ACETYLLACTOSAMINE Usage And Synthesis

Chemical Properties

White Crystalline Solid

Uses

A component of oligosaccharide portion of many N- and O-linked glycoproteins. It is a building unit for the antigenic determinants of a number of certain human blood group activities as well as of the ABH Type 2 determinants

Uses

N-Acetyl-D-lactosamine is used as a specific lectin target molecule in the identification and differentiation of sugar binding molecules such as the galectins. N-Acetyl-D-lactosamine is used in studies of galactosidase, fucosyltransferase, sialyltransferase, and lectin inhibition.

Uses

N-Acetyllactosamine is used in the expansion of a multi-funcational natural scaffold for the study of structural space of the Galectin-1-Ligand interaction. Also, it is used to identify the impurity as an imidazoline ring structure.

Definition

ChEBI: Beta-D-Galp-(1->4)-D-GlcpNAc is a disaccharide consisting of beta-D-galactose linked via a (1->4)-glycosidic bond to N-acetyl-D-glucosamine. It is a glucosamine oligosaccharide and a member of lactosamines.

Purification Methods

Purify N-acetyl-D-lactosamine by recrystallisation from MeOH (with 1 mol of MeOH) or from H2O. It is available commercially as a solution of 0.5g/mL of H2O. [Zilliken J Biol Chem 271 181 1955, Beilstein 17 IV 3452.]
